BRACKET AND BEAM CONNECTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a bracket capable of preventing rotation of a bolt inserted into a hole of the bracket on the axis thereof while ensuring aesthetic appearance of a guard fence.SOLUTION: A bracket (5) has a cylindrical member for connecting a post (1) and a beam (2) constituting a guard fence (100). The bracket has an insertion hole (53) into which a shaft (62) of a fastener (6) for holding the beam (2) is inserted. The insertion hole (53) has a shape that a small diameter hole part (53a), which has an outer diameter which is smaller than the outer diameter of a head (61) of the fastener (6), and a large diameter hole part (53a), which has an outer diameter which comes into contact with the head (61) of the fastener (6), are connected while being partially overlapped with each other.SELECTED DRAWING: Figure 2
【課題】ブラケットの孔に挿入されたボルトの、軸線を中心とした回転を防ぐと共に、防護柵の美観を損なうことを抑制する。【解決手段】防護柵（１００）を構成する支柱（１）とビーム（２）とを互いに連結する筒状部材からなるブラケット（５）であって、ビーム（２）を保持する締結具（６）の軸部（６２）が挿通される挿通用孔（５３）を有し、挿通用孔（５３）は、締結具（６）の頭部（６１）の外径よりも小さい外径を持つ１つの小径孔部（５３ａ）と、締結具（６）の頭部（６１）と接触する外径を持つ１つの大径孔部（５３ａ）とが互いに部分的な重なりを持って結合された形状を有する。【選択図】図２
